One Layer of Reflectarray Antenna Changing Beam Direction by Polarization

Abstract

Reflectarray antenna applies the reflection phase control function of a metal loaded frequency selective reflector to a reflector antenna, It is possible to control the reflection phases of vertical (V) and horizontal (H) polarization with a single reflectarray if the shape and arrangement of the elements are appropriately designed In this study, we investigate a high-precision reflectarray using three linear elements in a single-layer structure. The results of the analysis demonstrate that the mutual coupling between the H and V components is reduced, and the effect of manufacturing error is minimized. Consequently, it is inferred that the beam can be emitted in different directions for each polarization.
